PRODUCT DESCRIPTION

The AD8380 provides a fast, 10-bit latched decimating digital input that drives 6-channel high voltage drive outputs. The 10-bit input word is sequentially muxed into six separate high speed, bipolar DACs. Flexible digital input formats allow several AD8380s to be used in parallel for higher resolution displays. STSQ/CS, in conjunction with 3-bit addressable channel-loading pins, allows loading of the digital words either sequentially or randomly, and R/L control sets loading as either left to right, or vice versa. 6-channel high voltage output drivers drive to within 1.3 V of the rails to rated settling time. The output signal can be adjusted for dc signal reference, signal inversion or contrast for maximum flexibility.
